To all iciz'om it may concern i Be it known that I, lsimo S. STAHL, a citizen of the United States, residing at Bully, in the county of Berks and. litate of iennsylvania, have invented certain new and useful Improvements in Compositions for Artificial Woocl, 0* which the following is a specification. I

My invention relates to artificial Wood and whore particularly to compositions for male son that they shrink and become harcl like stone which deprives them of three important characteristics or my compositionsmoothness, flexibility uncl: the reception oi the comp-es. fore mutle become liarcl, not permit of the Yriringoi n Another superiority any other W1 3: ill will not shrinh 2-; hip ily i face which does not crscit. when the article is bent and which will take varnishwhich spring from the also will not crook or sur-- face.

My Coilli'jOslhlfill consists O1 water.

rosin,- mols. ses, crude petroleum espnsltnm. and plaster of Paris,

In the preparation of or" employ a oath-boiling sel in which i put approxinza ei pounds of glue anti fives-c rts i when the glue isthoroug 1y dissolved lL approximately twelve pounds of: powclerd rosim stirring the compound fr quently un-v til the rosin. is (lies li ed I then add n10- lasses, 'five quart more or less according to the flexibility tie lti. ll then boil and stir L gid the compounti unti. inolesses has becomethoroughly mixed with the other ingredients. I then mix in a separate vessel three quarts oit crude petrol um and approximately fourteen pounds of aspheltum at e 'empereture below the boiling point but sufic'iently high to melt the asphaltum and cause it to i) come thoroughly mixed with the petroleum. I then permit this preparation to cool off or drop t0 a temperature of about 175 Fa'h. and then add it to the first compound. The first compound must be kept at a boiling point while adding the combination of petroleum and asphaltum and th n the Whole kept at a boiling point for at least one-half hour. Frequent agitation or stirring is necessary-until the two prepsretions l we become thoroughlyn When the comg iouml has boiled a suticient length of time, say one-half hour, I atltl fifteen pounds plaster of Paris, or so much more or lessol plaster of Ieris as may be found necessary to bring the composition to the tlcsirecl consistenc When this is clone the composition is complete anti ready to bc moltietl into any desired form by any well known means, the composition being kept Warm until molclecl. H

Glue, rosin, asphaltum very semewh in bulls, and the exact quantity of eioh t he positivel t'ecl, but

I v the hold, is eas ly hendletl, and can be when from the :nol .l at once. i

{)i'nements male of this commie '-.-.iexpensive, durable, anti fieinole -ooth her-ti sut-i'see which will not-era's i bent or twist-eel, and which taste ver- 1 which will not creek if the is twelve pounds of glue dissolved in approxi mately live quarts of Water, approximately.

twelve pounds of rosin, approximately five quarts elf-molasses uccording'to the flexibility desired, approxii'nately three quarts of crude petroleum, and approximately fourteen pounds of asphaltum, and suilicient plaster of Paris to bring the composition to u plastic consistency that Willcpermit of molding it into any desired shape.

2. A composition consisting of twelve pounds of glue, five quarts of water, approximately twelve pounds of powdered rosin approximately five quarts of molasses, three quarts of crude petroleum, approximately fourteen pounds of asphaltum, and approximately fifteen pounds of plaster of Paris, substantially as and for the purpose described.

3. A compound for making a plastic imipossess tation of Wood comprising twelve pounds of glue, five quarts of water, twelve pounds of powdered rosin, five quarts of molasses, three quarts of crude petroleum, fourteen pounds of asphaltum, and fifteen pounds of plaster of Paris.

4. A compound for making a plastic imitation of wood comprising twelve pounds of glue, five quarts of water,twelve pounds of rosin, five quarts of molasses, three quarts of crude petroleum, 14 pounds of asphaltum;

and sufficient plaster of Paris to give the composition the degree of plasticity 118C637 sary to molding it into the shape desired.

In testimony whereof I hereto afiix my signature in the presence of two Witnesses.
